Concept explainers
(a)
Interpretation:
The configuration for the given moleculehas to be assigned.
Concept Introduction:
Priority rules:
- Priorities based on
atomic number
- H, -CH3, -NH2, -OH, -SH, -Cl, -Br, -I→ Increasing priority
- When priority cannot be assigned on the basis of the atoms bonded directly to the chiral center
-CH2 H, -CH2CH3, -CH2NH2, -CH2OH, -CH2Cl→ Increasing priority
- Atoms participating in a double or triple bond are considered to be bonded to an equivalent number of phantom atoms.
For example,
- Priority assignment is made at the first point of difference between groups (should not be based on the larger group).

- " is The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: :Ö: HO + Bicarbonate is crucial for the control of body pH (for example, blood pH: 7.4). A more self-indulgent use is in baking soda, where it serves as a source of CO2 CO₂ 2 gas, which gives bread and pastry their fluffy constituency. (i) Draw at least one additional resonance form. = (ii) Using curved "electron-pushing" arrows, show how these Lewis structures may be interconverted by movement of electron pairs.
